Single Loop Process Controller Instruction Manual

1.0 Introduction

The 53SL5100 Controller is capable of functioning as any one of four selectable application-specific (AS) instruments. The instrument application is selected with the front panel push buttons by entering the appropriate number (1 through 4 respectively) into a designated database location. The four instrument selections are:

1.

Single Loop (PID) Controller - a PID controller that fulfills the requirements of a majority of process applications. It is used with other devices in a standard feedback control loop to automatically control a process variable (PV) at a predetermined setpoint (SP). The proportional, integral, and derivative (PID) terms can be activated as needed.

2.

Analog Backup Controller - for operations requiring computer backup. It is used where a remote computer is normally controlling the final element directly. In this configuration, the controller acts as a control signal selector and as an automatic backup to the computer. The controller continually adjusts its output to match the feedback signal from the final element so that transfer to on-line operation is bumpless.

3.

Ratio (PID) Controller - for applications where one variable must automatically be maintained in definite proportion to another variable. The PID algorithm is executed to maintain a controlled line at a predetermined proportion to the uncontrolled or wild line .

4.

Automatic/Manual Station - for installations requiring a single station automatic/manual selector. In Auto , the Auto input is passed directly through the station to the output. In Manual , the station acts as a manual loader for direct operator control of the process.

Each of the four instrument selections has its own unique display of process attributes (e.g., process variable, output, etc.) as well as a supplemental parameter display that is invoked by pressing a front panel push button. The parameter display provides quick access to view and/or alter three values such as

% Proportional Band, Reset (integral action), and Rate (derivative action). The instrument is configured at the factory to display these three values, but the parameter display selections can be altered.

1.1 Scope of Book

Information in this book is presented as text, visuals, and tables. All three are required, but the text has been minimized wherever possible. The tables provide either summary information or procedural steps to perform a specific task.

Figure 1-1

illustrates the information layout of this book. The table in the figure summarizes the book sections that must be referenced as determined by the instrument application (e.g., Single Loop Controller, etc.), and if the instrument is pre-configured at the factory. Instruments that are not pre-configured at the factory have a standard factory configuration.

The sections of this book contain the following information:

Section 1, Introduction

: This section contains preliminary product and book information as well as the product specifications.

Section 2, Installation

: This section provides instrument mounting information, power wiring instructions, and signal wiring instructions.

Section 3, Front Panel

: This section provides illustrations that describe typical instrument displays; a general description of the front panel push button functions; and procedures to display a datapoint, alter a datapoint, default the database, and enter a password key. Also provided are operating procedures for the Hand-Held Configurer.

Section 4, Configuration Parameters : This section describes the data format types, the factory

standard configuration selections for the instrument, and presents the database configuration

Single Loop Process Controller Instruction Manual parameters in tables, by function.

Section 5, Single Loop (PID) Controller

,

Section 6, Analog Backup Controller

,

Section 7, Ratio (PID) Controller

, Section 8, Automatic/Manual Station

Sections 5, 6, 7 and 8 use the same structure for presentation, but differ in content. Each section provides:

• overview information of the instrument in a process loop,

• the block diagram of the instrument for that specific application,

• an explanation of the front panel push button functions,

• a configuration example of the display, and

• abbreviated configuration tables

Section 9, Parameter Display

: This section provides procedures to edit parameter values and to configure the Parameter Display.

Section 10, Instrument Tuning

: This section provides three methods to tune the instrument:

Trial and Error, Proportional Cycle, and Step Response (Ziegler-Nichols).

Section 11, EASY-TUNE

: This section provides information to initiate EASY-TUNE and to modify the tuning parameters. It also provides definitions of the tuning sequence status pa ra meters .

Section 12, Maintenance : This section provides the calibration information for the analog

input/output zero and span settings. It also has the hardware reset procedure, parts list, and illustrated parts breakdown of the instrument.

Appendix A, Discrete Contact Output CCO : This appendix illustrates various circuit layouts for

the Discrete Contact Output CCO0.

Appendix B, Communications : This appendix provides reference information for the binary

communication mode.

Appendix C, Database : This appendix lists all of the database parameters in alphanumeric

order.

The Series 53SL5100 Controller is supplied with an enclosure designed specifically for indoor mounting.

The installation site selected should be dry, well lighted, and vibration free. The ambient temperature should be stable and maintained within the specified minimum and maximum temperature limits listed in

Section 1.3, Specifications

, of this Instruction Bulletin .

The Controller can be supplied for use with a 24 V dc supply or 120, 220 and 240 V ac line service. Instrument power requirements are given on the instrument data tag.

2.3 Mounting

2.3.1 General

It is normally not necessary to open the instrument case during installation. If the instrument must be

removed from the case, refer to Section 12

for details. Incorrect procedures may damage the instrument.

The controller can be flush panel mounted, either as a single unit or side by side in multiple fashion. Appropriate mounting hardware is supplied by MicroMod. Outline dimensions and panel cutout requirements for case mounting are shown in

Figure 2-1

.

The dimensions given for spacing between instruments were selected on the basis of 1/8” thick panel strength. Panel strength must be considered when multiple case mounting is required. As the panel cut-out becomes longer it may be necessary to install supporting members. Because the panel area between instrument rows becomes weaker as the cut-out becomes longer to the point where the panel offers very little support. It is recommended that the 9 inch minimum center line dimension between horizontally mounted rows be increased as the number of units increases, or that the panel strip be stiffened.

The rear of the instrument case must be supported to prevent paneldistortion. Mount an angle iron or similar member along the bottom of the cases as indicated in

Figure 2-2

. If the panel is to be moved the instrument cases must be tied down to prevent damage.

If multiple mounted instruments are installed in a panel that tilts back, it may be necessary to support the instruments so the panel does not sag. The downward weight should be supported by additional panel supports and/or by increasing panel thickness.

2.3.2 Mounting Procedure

For single and multiple case mounting the instruments are furnished with a trim collar (mounting frame).

Figure 2-2

illustrates the installation and use of the trim collar (mounting frame). Trim collars (mounting

Installation 9

Single Loop Process Controller Instruction Manual frames) are available in various sizes and are supplied to conform with the particular panel cut-out.

✎ Note Mounting brackets and trim collars (mounting frames) are packaged separately. Check the shipment carefully to prevent loss of mounting hardware.

To install single or multiple mounted instruments in a prepared panel cut-out, proceed as follows.

1.

Remove the through-case shipping bolt.

2.

Slip the trim collar (mounting frame) over the rear of the case and slide it forward to the front of the case.

3.

Slide the instrument case through the panel opening.

a.

Single mounting case - support the weight of the case and attach the top and bottom mounting brackets. Tighten the bracket screws.

b.

Multiple mounted cases - MicroMod spacer bars and self-adhesive pads must be used between the cases, as shown in

Figure 2-3 . Start the installation from the right (when

facing the panel), installing the spacers as each case is added. Also, as each case is positioned in place, install and tighten the top and bottom mounting brackets. Each case must be tight against the previous case.

Note Spacers are not required on the outside of the right and left cases.

2.4 Connections

2.4.1 Preparatory

The 53SL5100A can be configured as a Single Loop Controller, Analog Backup Controller, Ratio Controller, or an Automatic/Manual Station. Therefore, prior to electrical interconnection, the particular instrument configuration should be determined with all assigned inputs and outputs identified to assure proper signal routing.

2.4.2 Wiring Procedure

Provisions for electrical interconnections are located at the rear of the instrument case. Under ideal conditions the use of shielded cable may not be required. In noisy locations all system input, output and power wiring should be enclosed in electrical conduit. System interconnection cables (except for power cables) should be fabricated from 2-wire shielded signal cable. Signal transmission distance should not exceed the limit specified for the particular transmitter (refer to applicable technical literature provided for the respective device). Polarity must be observed when connecting the remote transmitters to the controller.

The controller has a vertically mounted terminal board (TB1) for signal interconnections and a horizontally mounted terminal board (TB2) for power wiring. Both terminal boards are located at the rear of the instrument case.

SNAP-OUT

TERMINAL STRIPS

Both terminal boards, TB1 and TB2, have removable plug-in connector strips. The upper strip for TB1 has connectors 1 through 12 and the lower strip has connectors 13 through 22. All of the connectors are on a single strip for TB2. To remove a connector strip, grasp it securely on both sides with the thumb and forefinger and pull it straight out. Each strip is keyed and has one scalloped side so that after the wires are connected, it can not be inadvertently misaligned when inserted.

Note

Warning

The screw terminals on the back of the instrument are designed for

12 - 24 AWG wire. It is important that the wire be stripped to expose

1/2 inch of conductor before installation.

Instruments that are powered from an ac line service constitute a potential electric shock hazard to the user. Make certain that these system ac power lines are disconnected from the operating branch circuit before attempting electrical interconnections.

2.4.2.1 Power Input (As Specified)

2.4.2.1.1 DC Power

Reference Figure 2-4 and connect the remote 24 V dc power supply to the controller, as follows:

1.

Connect (+) input line, via remote SPST switch, to terminal L1 .

2.

Connect (-) input line to the system bus bar. The bus bar should be connected to a good earth ground (#8 AWG wire is recommended). Individual wires should be run from the controller

Power Common ( PC ) and Signal Common ( SC ) terminals to the bus bar. The chassis should be grounded by connecting terminal G to earth ground.

Installation 13

Single Loop Process Controller Instruction Manual

✎ Note Use of a common bus bar is recommended to minimize potential voltage differences that may occur as the result of ground current loops, e.g., potential difference between separate signal grounds, power grounds, etc.

2.4.2.1.2 AC Power

Reference Figure 2-4 and connect the specified line service (110-120, 220-240 V ac, 50 or 60 Hz) to the

controller, as follows:

1.

Connect the phase or hot line L , via a remote power disconnect switch or circuit breaker, to terminal L1 .

2.

Connect the neutral line N to terminal L2 for 110-120 V ac. Connect the neutral line N to terminal L3 for 220-240 V ac.

3.

Connect Power Common to a good earth ground (#12 AWG wire is recommended).

4.

The instrument case should be grounded by connecting terminal G to earth ground at the source of supply (green/green-yellow ground).

5.

Notes All supply connections include surge protection rated at 275 V ac normal mode.

To minimize possible interference, ac power wiring should be routed away from signal wiring.

2.4.2.2 Current / Voltage Input to ANI0 and ANI1

When the input signal is from a 4-20 mA current transmitter, a precision 250 ohms (± 0.1%) resistor is required. (The resistor tolerance is critical, as the resistor is used to accurately convert the current signal from the transmitter, which is typically 4-20 mA, to a specified analog input voltage of 1 to 5 V dc). The back of the rear terminal board has the appropriate resistors ( R1 and R2 , respectively ) for ANI0 and ANI1.

If the input signal is already a voltage signal, its corresponding resistor should be removed.

2.4.2.3 Contact Input to CCI0

A separate contact input signal to CCI0 can be used for remote enabling of the setpoint, computer control, or auto control depending on the controller mode of operation. One side of each remote contact must be connected to power common as illustrated in

Figure 2-4

. Minimum opened or closed recognition time for the remote contact must be 0.05 seconds.

2.4.2.4 Current Output From ANO0

A current output signal is available for transmission to the process final control element. The current output signal, 4 to 20 mA, will vary in direct proportion to the process variable being displayed, e.g., volumetric flow rate, mass flow rate, operating pressure, etc.

Observe proper polarity when connecting the controller to the remote analog instrument.

2.4.2.5 Contact Output CCO0

A discrete contact output (CCO0) is identified in

Figure 2-4 . The discrete output is a solid state switch with

a rating of 30 V dc, 50 mA maximum. It is referenced to power common.

14 Installation

Single Loop Process Controller Instruction Manual

The contact output is assigned and used depending on the controller configured mode of operation.

When this contact is connected to an inductive load, an external arc suppression network is required for contact protection.

2.4.2.6 Datalink Connections

Datalink is an interrogator/responder serial interface capable of supporting 32 instruments on a single network. It uses an RS485 physical interface. The Datalink wiring diagram for this instrument is provided as

Figure 2-5

. Complete coverage of the Datalink is provided in the SUPERVISOR-PC Instruction Bulletin

53SU5000 .

2.4.3 Factory Set Calibration

Each unit contains individual factory set entries that calibrate the two analog inputs and analog output.

There is a calibration sheet supplied with each instrument that should be retained for future reference when the installation is completed. Refer to

Section 12.3

for additional information.

2.5 Grounding

Installations are expected to have access to an independent, high quality, noise-free point of earth reference. The system should be connected by a dedicated, low resistance (less than one ohm) lead wire directly to the installation’s point of earth reference. This ground reference is referred to as the Instrumentation Ground. If an instrumentation ground reference does not exist in the installation, an earth ground electrode should be established with an independent grounding rod or groundgrid mesh. Grounding connections are described in

Section 2.4.2.1.1

and

Section 2.4.2.1.2

.

3.0 Front Panel

3.1 Front Panel Introduction

The front panel of the instrument contains the display and all push buttons used to change display presentations and parameters. The front panel has a gas discharge 96 X 48 dot matrix display, a six pushbutton vertical keypad, and a four pushbutton horizontal keypad. It also has a configuration port DIN plug, which is concealed behind the identification tag pull-down door. To open this door, press on the lower front edge.

Front panel display information is presented as bar graphs with associated alphanumerics or as alphanumerics only. (See

Figure 3-1

.)

Figure 3-1. Front Panel

3.2 Front Panel Display

The bar graph display is a visual indication of the process events monitored and subsequently altered either by the instrument or other device. This instrument provides three unique bar graph displays and one alphanumeric parameter display. Bar graph response dynamics as well as the alphanumerics on all of the display types are selected when the instrument is configured.

There are four configurable operating modes, called control strategies ( CS1-4 ). The control strategies are:

• CS1, Single Loop PID Controller

• CS2, Analog Backup Controller

• CS3, Ratio Controller

• CS4, Automatic/Manual Station

Two of the control strategies, CS1 and CS2, have identical bar graph presentations; that is why there are three, rather than four, unique bar graph types. Each control strategy (CS1 - CS4) also has a pushbutton

Front Panel 19

Single Loop Process Controller Instruction Manual selectable parameter display. Although the contents of the parameter display are selectable configuration items, the display format is identical for each of the four control strategies.

Any display type can have a portion of its contents overlaid with an ALARM indicator. If the instrument is manually set to engineering mode, the display can be overlaid with the CONFIGURATION or DISPLAY data entry line. Alarm indicators warn of variation changes that exceed tolerance limits; the process may require immediate attention. The engineering mode (EMODE) overlay provides a single entry line for data display and alteration.

The three bar graph display types for CS1-4 and the parameter display, with appropriate call outs, are illus-

trated in Figure 3-2 through

Figure 3-5 . Figure 3-6

and Figure 3-7

illustrate displays with alarm and configuration overlays.

3.3 Front Panel Pushbuttons

The front panel pushbuttons are used to vary the display presentation, to select instrument operator or engineering modes, and to select local or remote setpoint levels. In engineering mode, (EMODE) they are also used to display and/or alter database parameters which are presented as single line datapoints in the configuration overlay.

Pushbutton operator mode functions differ slightly with each control strategy implemented; however, the engineering mode pushbutton functions are identical for all four control strategies.

General pushbutton functions are illustrated in

Figure 3-8

below and defined in Table 3-1 on the facing

page. The summary table in

Figure 3-8 shows the functional differences of the push buttons by control

3.3.3 Defaulting the Database

Defaulting the database sets all non-instrument-specific datapoint parameters to predetermined values, then suspends the instrument which is indicated by the logo presented on the display. When instrument operation is suspended, instrument algorithmic control ceases.

The procedure to default the database is presented in

Table 3-4

and the display logo is illustrated in

Figure 3-13 . Entering a 98 in datapoint B00 defaults the database. If it is desired to suspend instrument

operation without defaulting the database, enter a 00 in lieu of a 98 into B00. The defaulted database val-

ues are provided in the configuration tables of Section 4

and the database tables in Appendix C, Database

, under the column headed Default . Those parameter values that are left unaltered when the database is defaulted are identified with gray-tone shading in the Default column of the tables. It should be noted that

3.4 Front Panel Pushbutton Alternatives

There are four alternative methods other than the front panel push buttons for accessing and changing database parameters. All four methods to display and/or alter database parameters are listed as follows:

1.

Using an IBM PC compatible computer running the MC5FIG.EXE configuration program that is supplied as part of the 53HC3300 software package. This procedure is included in the instructions with the software.

2.

Using an IBM PC compatible computer running the configuration program that is supplied as part of the 53WS5000 software package. This procedure is included in the instructions with the software.

3.

Using a SUPERVISOR-PC with configuration software. This procedure is provided in the

SUPERVISOR-PC Instruction Bulletin (IB 53SUS000) .

4.

Using the MicroMod Hand-Held Configurer (or any ASCII RS-232 terminal) connected to the configuration port DIN plug on the front panel of the controller. This procedure, using the

Hand-Held Configurer, is described in the remainder of this chapter.

Figure 3-15 illustrates the Hand-Held Configurer and PC DIN plug cables necessary to configure an instru-

ment for the four alternative methods described. The PC cable type (9 pin or 25 pin) is dependent upon the

3.4.1.3 Altering a Database Parameter

To modify a value or enter a new value press P and the parameter ID followed by

E NTER . Then press the keys corresponding to the value to be assigned, followed by

E NTER . For example, to set B00 to 97 to initiate the display test, press:

P B0 <ENTER> 097 <ENTER>

Values entered with the PUT command P must be formatted as follows:

In general, all modification inputs are limited to the first ten characters of the field.

For B data type parameters, the value entered must be between 0 and 255.

For L data type parameters, the value must be 1 or 0.

All responses are completed by pressing E NTER .

Pressing E NTER after pressing P automatically recalls the last database parameter.

Pressing N after pressing P causes the next parameter of the same data type to be displayed. (The NEXT command N only works with index numbers below 256.)

3.4.1.4 Setting or Changing a Password Key

As a security feature, the instrument can be configured so that a password key is required to access the

Engineering Mode configuration function. The password key can only be set by the Hand-Held Configurer, or the 53HC3300 or 53WS5000 software packages via a PC, or SUPERVISOR-PC, and not by the instrument front panel keys.

A password key is a special data type ( Q1 ) that is displayed or configured just like any other data type using the Hand-Held Configurer. The value assigned to a password key must be an ASCII numeric string

Front Panel 37

input characters. To remove a password key completely, press C TRL 0 (hold C TRL and press 0), then E NTER .

3.4.1.5 Storage Cartridge Transfer

The procedure for saving or loading the database or calibration constants of an instrument to/from a storage cartridge is as follows:

1.

Insert the cartridge containing the desired database in the HHC. The cartridge is inserted by placing it into the recess at the back of the HHC with the cartridge label facing outward and up, then sliding the cartridge down until it is firmly seated. When loading to the instrument, verify that the write protect switch (when present) on the cartridge has been pushed to its outside position. When saving to the cartridge the write protect switch must be toward the inside.

2.

To initiate the TRANSFER operation, press T at the command entry point. The following menu appears:

MEMORY TRANSFER

F1-TO CONTROLLER

F2-FROM CONTROLLER

3.

Press either F1 or F2 to select the desired operation. Pressing C TRL -C aborts the operation.

Depending on which selection is made, one of the following two menus is displayed: a.

If

F1

is selected, the following menu appears:

F1-CALIBRATE

F2-DATABASE

F3-PROGRAM (not applicable for this instrument)

Based on which selection from this menu is made the following operations can occur:

• F1-CALIBRATE : This selection copies the calibration values of the standard analog inputs and outputs to the controller. These are values that were previously saved to the storage cartridge with a memory transfer from the controller. This transfer takes approximately 1 second.

• F2-DATABASE : This selection copies the database, less the calibration values, and the assigned instrument address to the instrument. Transfer takes approximately 12 seconds.

• F3-PROGRAM : This selection is not applicable for this instrument.

b.

If F2 is selected, the following menu appears:

FP-DATABASE

F3-PROGRAM (not applicable)

Based on which selection from this menu is made, the following operations can occur:

• F2- DATABASE : This operation copies the entire database, all B, L, C, H, A, and F datapoint values, in the instrument to the storage cartridge. Transfer takes approximately 12 seconds.

• F3- PROGRAM : This operation is not applicable forthis instrument.

When the transfer begins, a message is displayed indicating the transfer has started. Another message appears when the transfer is completed. If the transfer fails, an error message is displayed instead of the transfer completed message. If an error does occur, resolve the cause and re-initiate the transfer. A transfer error should not be ignored, as a partial transfer may cause the HHC cartridge to contain corrupted data. The HHC returns to the command entry mode if the transfer is successful or if it is halted with an error message.

4.0 Configuration Parameters

The configuration parameters provide the latitude to define the instrument’s personality attributes , so that while still functioning within its designed specifications, it can perform application requirements with greater refinement.

Typical configuration parameters are the fine tuning variables to set the instrument’s responsiveness: the indicator zero point and span; the display tag names; engineering units of the process variable; and alarm limits, etc. IT IS NOT NECESSARY TO DEFINE ALL OF THE CONFIGURATION PARAMETERS , as commonly used preset values may not have to be altered, certain parameter selections eliminate others, and the process application itself may not require specific instrument attributes.

Although all resident in a memory database as datapoints , the configuration parameters are clustered into modular groups that may have specific hardware identities (e.g., the ANI, ANO, CCI, and CCO circuits

illustrated in Figure 4-1

through

Figure 4-4 ), or may represent software-controlled functions that are not

specific to any one hardware element.

4.1 Datapoint Types

A parameter can be any one of six data types. Each data type represents a specific data format: integers, alphanumeric text strings, etc. A database module containing multiple parameters can have a mix of data

types. The data types are defined in Table 4-1 .

Table 4-1. Datapoint Types

42 Configuration Parameters

Single Loop Process Controller Instruction Manual

4.3 Configuring the Database Modules

The datapoints in the database modules must be changed to reflect required alterations in the factory standard configuration or when the instrument is re-configured.

There are generally four datapoint parameter types contained in the eight database modules. The parameter types affect Datalink communications, display indications, input-output signals, and instrument

responsiveness. The eight database modules are described in Table 4-3

.

Although it is not an absolute criterion, it is assumed the modules will be configured in the table Item order; however, if the instrument is to be connected to a Datalink network, item 7, Communication Module, should be configured first. By configuring the Communication Module first, the remaining datapoint values can be entered via the 53SU5000 PC configuration option, as described in IB 53SU5000 .

Table 4-3 is also a pointer to the descriptions of the database modules; the descriptions are presented as

Table 4-4 through

Table 4-11 . (The gray tone shading in the default cell of a datapoint indicates the

datapoint contents are left unchanged after default.)

5.0 Single Loop (PID) Controller

5.1 Single Loop (PID) Controller Operation Overview

In a standard feedback control loop, the Single Loop (PID) Controller functions as the primary processing unit. When the process is altered due to disturbances (e.g., flow rate changes), the controller gauges this change from the process variable (PV) feedback signal sent to it by a process measurement instrument

(e.g., flow meter) in the loop.

The controller compares the feedback signal to the setpoint level and calculates the required error correction, which is applied as an output signal to the final control element (e.g., valve) in the loop. The final control element responds to alter the process (manipulated variable) toward a predetermined operational setpoint (SP), which can be set locally at the controller front panel or remotely from another instrument. If the process variable exceeds tolerable limits of change, the controller activates a signal to an alarm. These

events are illustrated in Figure 5-1

.

Figure 5-1. Standard Feedback Control Loop

Process variable feedback input (Analog Input) received from the process measurement instrument is typically 1-5 V dc, 4-20 mA dc. The Single Loop Controller zero and span inputs for this signal are calibrated by the factory and should not be altered. The controller is defaulted to display the process variable input as a percentage value determined by input signal amplitude; however, it can be configured to display direct units of measurement (e.g., gallons per minute [GPM]).

The setpoint value is received from another device (e.g. Single Loop Controller, PC, host computer, etc.), or is manually entered at the controller front panel.

✎ Procedure

Note

To minimize sudden process changes, adjust the local setpoint value to the original remote setpoint value before switching back to remote setpoint control (Remote).

It is the difference between the setpoint (SP) and received process variable (PV), augmented by the action of the tuning constants Proportional Band, Reset Time, and Rate Time, that determines the required output

Single Loop (PID) Controller 55

Single Loop Process Controller Instruction Manual to the final element to restore the process. The output signal (Analog Output) to the final element is 4-20 mA dc. This signal is also factory calibrated for zero and span, and should not be altered. On the controller display, the output signal value correlates to the desired control element operation (e.g., an output of 100% equals a 20 mA signal amplitude, which causes a valve to be fully opened or closed, depending on the reverse valve setting in the Single Loop Controller).

Single Loop Controller output response characteristics to the process changes are determined by Proportional, Integral, and Derivative parameters (also called PID constants). The controller PID constants, as well as other controller functions (e.g., reverse valve), can be defined with configuration datapoint parameter entries. The PID general response characteristics are defined in

Section 10, Instrument Tuning .

As illustrated in Figure 5-2

, Single Loop Controller Block Diagram, when a 1 is loaded into System Module datapoint B00 to initiate CS1, the signal designators are as follows:

1.

ANI0 = Process Variable Input

2.

ANI1 = Remote Setpoint Input

3.

6.0 Analog Backup Controller

6.1 Analog Backup Controller Operation Overview

The Analog Backup Controller is used in operations where a remote computer is normally controlling the final element directly. In this process configuration, the controller functions as a signal selector and automatic backup unit to the computer. The controller assumes process control in the event of a signaled com-

puter failure. The Analog Backup Process Configuration is illustrated in Figure 6-1 .

Figure 6-1. Analog Backup Process Loop

The Analog Backup Controller operates as a Single Loop (PID) Controller (see Section 5

) when driving the process final element. While in backup and automatic, the controller continually adjusts its output to match the feedback signal from the final element (Analog Input 1) so that transfer to on-line operation is bumpless in the event of computer failure.

Selection of the computer or backup controller signals to the process final element is performed by the controller’s CCO modules (CCO0 and CCO1) in conjunction with blocking diodes (see circuit diagram of gray-tone area equivalent in

Figure 6-1

).

The computer drives the final process element when remote operation is selected at the controller front panel via the R/L push button and if CClO’s contact is closed; otherwise, the computer’s control signal is diverted and the controller is active. ANO0 drives the process final element (20 mA computer / 4 mA controller) when backup control is active.

As illustrated in

Figure 6-2 , Analog Backup Controller Block Diagram, when a

2 is loaded into System Module datapoint B00 to indicate CS2, the signal designators are as follows:

7.0 Ratio (PID) Controller

7.1 Ratio (PID) Controller Operation Overview

The Ratio (PID) Controller is used where one variable, called the controlled variable, must be automatically maintained in definite proportion to another variable, called the wild variable.

Transmitting meters (e.g., flow meters) must be installed in each variable line. Signals from the controlled and wild variable meters (Analog Input 0 and Analog Input 1, respectively) are received by the Ratio Controller, which compares them and calculates the required correction that is applied as an output signal

(Analog Output 0) to a final control element (e.g, valve) in the controlled variable line. The final element in the controlled variable line is controlled to alter line throughput so that the predetermined ratio between the two lines is maintained.

The predetermined ratio is set at the controller front panel with the Ratio/Local (R/L) pushbutton in R . If the proportion between the wild variable and the controlled variable can not be maintained, the controller activates a signal (CCO0) to an alarm. These events are illustrated in

Figure 7-1

.

Figure 7-1.

Ratio (PID) Controller Process Loop

While in Ratio ( R ) control, the setpoint pushbuttons modify the desired ratio value (controlled variable to wild variable) by altering the location of the ratio tick bar, which is immediately covered by the setpoint arrow indicator when the push button is released. Because the setpoint indicator moves to cover the ratio tick bar, altering the ratio setting indirectly affects the setpoint value. When in Local ( L ) control, the pushbuttons modify only the setpoint value. In Local control, the controlled variable line functions as a Standard

Feedback Control Loop (see Section 5 ).

Ratio (PID) Controller 75

Single Loop Process Controller Instruction Manual

✎ Procedure

Note

To minimize sudden process changes, adjust the local setpoint value to cause the setpoint pointer to cover the ratio tick bar before switching to ratio control (Ratio).

As illustrated in

Figure 7-4

illustrates how a Ratio Controller would appear with only the default values and power applied, but no analog input or output signals. In

Figure 7-4 , ANO0 (TB1-10) is jumpered to ANI0 (TB1-2) to simu-

late process operation. The unit has the AC power supply and power cord 173D109U03. Connecting

ANO0 to ANI0 is done only for illustration purposes and is not necessary to configure the controller. If the controller is connected to a Datalink network, then assign the Instrument Address (B001) and Baud Rate

(B002) first so the remaining datapoints may be entered at the SUPERVISOR-PC unit.

After this section, refer to

Section 9

to configure the parameter display datapoints. The parameter display is accessed by pressing the F2 push button from this display. Also, refer to

Section 10.0, Instrument Tuning , or

Section 11.0, EASY-TUNE , to set the operating performance parameters: Proportional Band

8.0 Automatic/Manual Station

8.1 Automatic/Manual Station Operation Overview

The Automatic/Manual Station is a conventional single station selector. In Auto , the auto input (Analog

Input 0) is passed directly through the station to the output (Analog Output 0). In Manual , the station functions as a manual loader, allowing the output to be controlled from the front panel pushbuttons.

If the process variable (Analog Input 1) exceeds tolerable limits of change, the station activates a signal

(CCO0) to an alarm. The process variable feedback signal is not used to generate an output for final element control of the process, but is displayed for visual indication of the process status. These events are

illustrated in Figure 8-1

.

Figure 8-1. Automatic/Manual Station Output Control

As illustrated in

9.0 Parameter Display

The parameter display can be accessed from any control strategy (CS1 - CS4) by pressing the F1 or F2 front panel push button. It provides convenient access to view and/or alter three parameter datapoint values that were selected when the display was configured. (The option to view and alter any parameter datapoint value with EMODE is still available.)

When modifications are allowed, the arrowhead indicates which parameter is selected, and is positioned by the setpoint up/down push buttons. Pressing F3 copies the value to an edit line that displays at the bottom of the screen.

The datapoint is edited as it would be for the Engineering mode configure operation:

• The setpoint up/down push buttons are used to select the value.

• The output push buttons are used to shift the character string left or right, as necessary.

• Pressing

F3

again copies the value into the parameter that was selected.

• Pressing F1 abandons the edit procedure.

Note that the Modify Disable ( L313 ) datapoint must be 0 ; otherwise, datapoint value alteration from the parameter display is prohibited ( Modify Disable is set to 1 ). The edit procedure is summarized in

Table 9-1

and the parameter display is illustrated in Figure 9-1 .

10.0 Instrument Tuning

Tuning the instrument is an iterative process to refine the Proportional Band (PB), Integral (also called

Reset Time [TRI]), and Derivative (TD) parameters of the Control Module 0 (CON-0).

The three parameter datapoints are C106, Proportional Band (PB); C107, Reset Time (TR); and C108,

Derivative Time (TD). Values for these three datapoints determine the proportional, integral, and derivative action of the instrument so that its output properly alters the final control element setting to correct the effects of a disturbance to the process or a setpoint change.

10.1 Proportional Action (PB)

In Proportional action there is a comparative relationship between the controlling instrument output signal magnitude and the calculated error, which is the difference between the process variable and the setpoint.

The proportional action of a controller is set as a percentage of the proportional band (% P.B.). Percent proportional band is the full scale through which the error signal must vary to cause full scale output variation due only to proportional control mode response. The proportionality factor between the output signal and the error is called the gain .

Gain = 100 / % P.B.

If a small percent change in error is required to cause a full scale output variation from the final control element (narrow proportional band), then the process system has a high gain . For example, with the setpoint at 50% of scale and a percent proportional band at 20%, the process variable feedback signal must vary from 40% to 60% of scale to make the final control element vary through its full stroke. The gain would be

100 / 20 = 5.

If a large percent change in error is required to cause a full scale output variation from the final control element (wide proportional band), then the controller is set for low gain . The datapoint to set the % P.B. parameter is C106; it has a default value of 100%. The minimum value for proportional band is 2% and the maximum value is 1000%; 0 is off.

10.2 Integral Action (TR)

Integral action augments proportional action to cause the controller to drive the final control element until the error is completely nulled. It produces a corrective signal proportional to the deviation and the length of time the controlled variable has not been at setpoint. Integral action is expressed as the length of time in minutes required for it to produce an output change equal in magnitude to that produced by proportional action.

The datapoint to set the Reset parameter is C107; it has a default value of 0 minutes (no integral action).

The minimum value for integral action is 0.02 minutes and the maximum value is 200 minutes.

Integral action datapoint C107 must be 0 minutes if Manual Reset, datapoint C111 is used in lieu of integralaction. The default value for Manual Reset is 50%. The minimum value is 0% and the maximum value is

100%.

Instrument Tuning 99

Single Loop Process Controller Instruction Manual

10.3 Derivative Action (TD)

Derivative action augments proportional action by responding to the rate of change of the process variable.

It is used to make the controller more responsive to sudden process disturbances.

The datapoint to set the Rate parameter is C108; it has a default value of 0 minutes.

The minimum value for derivative action is 0.01 minutes and the maximum time is 8 minutes; 0 is off.

The derivative time in minutes is the amount of time by which the proportional action (or proportional plus integral action) is advanced.

10.4 Instrument Tuning

Table 10-1

provides summary information for the tuning parameters referenced in the three tuning methods that follow. The Trial and Error Method (

Table 10-2 ) is usually preferred for processes that respond

quickly, requiring no waiting to determine steady cycling process conditions. The Proportional Cycle

Method ( Table 10-3

) and Step Response Method (

Table 10-4 ) are expedient procedures for slow pro-

cesses. See

Figure 10-1

Procedure

Set the process to approximately normal conditions in Manual mode.

Set TR (C107) first to minimum value (0.02 minutes) for several moments, then set it to the extreme maximum (200 minutes) to lock in a fixed reset value.

Set P.B. (C106) to the widest value (1000%).

Set TD (C108) to the lowest value (0.01 minutes).

Switch to Auto mode.

Slowly reduce P.B. (C106) until process cycling starts.

Increase TD (C108) slowly until process cycling stops.

Reduce P.B. (C106) until process cycling starts again.

Further increase TD (C108) until cycling stops again.

Repeat Steps 8 and 9 until no improvement can be made when TD is increased.

Increase P.B. (C106) to a safe margin approximately 1.5 times the value attained in

Steps 8 through 10.

Procedure

Set the process to approximately normal conditions in Manual mode.

Set TR (C107) first to minimum value (0.02 minutes) for several moments, then set it to extreme maximum (200 minutes) to lock in a fixed reset value.

Set P.B. (C106~ to the widest value 1000%).

Set TD (C108) to the lowest value (0.01 minutes).

Switch to Auto mode.

Slowly reduce P.B. (C106) until process cycling starts.

When a slight cycle is repeatedly established, measure the peak-to-peak period of oscillation and record it as T minutes.

Observe the P.B. setting and record it as P .

Compute the best settings as follows:

A. Proportional & Integral (PI): P.B. = 2 (P), TR = 0.8(T)

B. Proportional & Derivative (PD): P.B. = 0.8(P), TD = 0.12(T)

C. Proportional, Integral, and Derivative (PID): P.B. = 1.5(P), TR = 0.5(T), TD = 0.12(T)

Procedure

Set the process to approximately normal conditions in Manual mode.

Introduce a 10% (approximate) step change to the manually regulated signal to the valve. Observe the magnitude of the step in percent of full signal span F . Also plot a graph of the resulting transient curve traced by the controlled variable.

Draw a straight line tangent to a point on the curve having the greatest slope (most linear).

Measure the apparent dead time L in minutes as shown in

Figure 10-1

.

Measure RL, the product of the slope and dead time as shown in

Figure 10-1 . This

value should be expressed in percent of full scale span.

Compute the best settings as follows:

A. Proportional (P): P.B. = (100 RL)/ F.

B. Proportional & Integral(PI): P.B. = (100 RL)/ F, TR = 3L

C. Proportional, Integral, and Derivative (PID): P.B. = (80 RL)/ F, TR = 2L, TD = 0.5L

11.0 EASY-TUNE

The EASY-TUNE algorithm is used to help determine the optimal tuning values for the Proportional Band

(PB), Integral (TR), and Derivative (TD) parameters (called PID constants) in the Controller Module Mode

0 (CON-0). The three parameter datapoints are C106, Proportional Band (PB); C107, Reset Time (TR); and C108, Derivative Time (TD).

This section provides the necessary information to initiate the EASY-TUNE sequence, to identify the

EASY-TUNE parameters, to evaluate the return status indications, and to modify the tuning criteria.

11.1 General Considerations

An instrument functioning in a process as a pure integrator can not be tuned with EASY-TUNE, as there is only one instrument value which eliminates the ability for instrument self regulation.

For processes with slow variable changes, be sure the Process Variable is at a steady state before initiating the EASY-TUNE sequence.

Disturbance to the process during the EASY-TUNE sequence may result in a false process characterization.

Feed Forward control is not allowed during the EASY-TUNE sequence.

In some applications, a process response may not be satisfactorily approximated as a first order time lag with gain and dead time.

If the ratio of process Dead Time ( W P ) and Process Time Constant ( T P ) is greater than 0.5, datapoint B386 should be set to 3 for PID Control Mode.

11.2 Initiating the EASY-TUNE Sequence

The EASY-TUNE algorithm is initiated when datapoint B008, Background Program, is set to 1 . Datapoint

B385, Control Module Selector, must be checked to ensure it is at its default value of 0 for CON-0.

11.5 Modifications to Tuning Criteria

During EASY-TUNE sequence execution, each of the three algorithm variables: Time Constant ( T P ),

Process Gain ( K P ), and Dead-Time ( W P ), are altered by 10% in the conservative direction, (instrument operating characteristics would be slower response, but less chance of oscillation and instability) before

the tuning parameters are computed using the ITAE equations listed in Table 11-4

. ( Figure 11-2 illustrates

the equation variables with respect to the response curve.)

The three variables T P , K P , and W P can be increased numerically to compute tuning parameters that are more conservative, or decreased for less conservative tuning parameter calculations (instrument operating characteristics would be faster response and greater chance of instability or oscillation). Parameters used to alter the variables are the EASY-TUNE Modifiers, datapoints C382 ( T P Modifier), C383 ( D P Modifier), and

C384 ( W P Modifier). It is recommended that the values entered in C382, C383, and C384 be between -0.5 and 0.5. The effect on the equation variables is as follows:

T P modified = T P (1 - C382)

K P modified = K P (1+ C383)

W P modified = W P (1+ C384)

11.6 Aborting the EASY-TUNE Sequence

If the EASY-TUNE sequence is active and the instrument output is deliberately changed, the sequence will be aborted. The original instrument output and Manual or Auto mode will be restored. Datapoint B387,

EASY-TUNE Status, will be set to 54 .

If the EASY-TUNE sequence is active and datapoint L521, EASY-TUNE Abort Switch, is set to 1 , the sequence is immediately aborted. The original instrument output and Manual or Auto mode will be restored. Datapoint B387, EASY-TUNE Status, will be set to 60 .

11.7 EASY-TUNE Sequence Completion

Upon successful completion of the EASY-TUNE sequence, the instrument is returned to its original status, with or without the new tuning parameters, depending on its initial settings. If the EASY-TUNE algorithm encounters an abnormal event, the instrument is returned to its original settings and an error status is displayed in datapoint B387.

12.0 Maintenance

✎ Note The factory set calibration constants for ANI0, ANI1, and ANO0 are applicable only for the main printed circuit board supplied in the particular controller. This data is recorded on a calibration sheet supplied with the controller. The data should be retained to facilitate easy field recalibration in the event one or more of the constants is inadvertently changed.

12.1 Service Approach

This instrument is a microprocessor-based device; all mathematical computations, data manipulation, and sequencing operations are software controlled. After the instrument has been configured, normal operations are controlled via the front panel push buttons. Because the controller does not have internal circuitry that requires field adjustment, diagnostic testing and preventive maintenance are not required to be performed.

Generally, when a process malfunction occurs, it usually manifests itself as a controller problem, even though it might be a defective process variable monitoring device, remote transmitter, or interconnecting wires. These associated remote devices should be checked before attempting controller troubleshooting and repair.

Due to the complexity of microprocessor-based instruments, attempting fault finding analysis on integrated circuits (ICs) on the main printed circuit board (PCB) is not recommended. The ICs are static-sensitive and can be damaged if not properly handled. Also, when test probes are connected, even a momentary short across several IC pins with a probe tip can damage the IC. Therefore, only trained technicians familiar with

CMOS technology and microprocessor functionality should be permitted to service the equipment.

12.2 Parts Replacement

Warning ALWAYS REMOVE POWER BEFORE ATTEMPTING TO INSTALL,

DISASSEMBLE, OR SERVICE ANY OF THE EQUIPMENT.

FAILURE TO REMOVE POWER MAY RESULT IN SERIOUS

PERSONAL INJURY AND/OR EQUIPMENT DAMAGE.

You can access the internal instrument parts by removing the front display panel:

1.

Insert a small screwdriver into the notch at the top center of the display.

2.

Twist the screwdriver to depress the retaining latch.

3.

Hold the upper sides of the display and pull forward as the latch is depressed.

4.

Disconnect the cable at the rear of the front display panel from its socket. The other cable end connects to the main printed circuit board.

To replace the display unit:

1.

Reconnect the display end of the cable to the new front display panel.

2.

Insert the extended portion of the display panel into the instrument cabinet.

3.

Latch it in place with a screwdriver.

After the front display panel is removed, the main printed circuit board can be accessed. The main printed circuit board has the power supply as well as the microprocessor circuitry.

Maintenance 113

Single Loop Process Controller Instruction Manual

To remove the main PCB:

1.

Use the PCB’s front edge board ejector to pull it free from the rear terminal board slot, and carefully slide it from the case.

2.

If a situation arises requiring technical assistance, contact the nearest MicroMod Automation field office.

Note When communicating with MicroMod Automation for replacement of the main PCB, refer to the serial number of the unit to ensure the correct replacement assembly is supplied. The necessary ordering information is provided on the instrument data tag and on the manufacturing specification sheet supplied with that particular controller.

In the event of a hardware malfunction, a replacement PCB can be quickly substituted for the defective assembly to minimize downtime. Contact MicroMod Automation for instructions before returning equipment. The defective PCB should be carefully packaged and returned, shipping charges prepaid, to the

Repair Dept. of MicroMod Automation. Do not wrap PCBs in plastic, as it can cause static damage . It is suggested that the defective PCB be returned in the special bag in which the replacement module was supplied.

12.3 Calibration

The controller’s analog inputs (ANI0 and ANI1) and output (ANO0) are extremely stable. They normally do not require recalibration. If it becomes necessary to recalibrate the instrument, due to the inadvertent change of the stored calibration values, then this can be accomplished by altering their respective datapoints. The calibration span and zero datapoint locations are shown in

Table 12-1 .

Appendix A: Discrete Contact Output CCO

The discrete output CCO is not a mechanical contact closure but an NPN Transistor that is analogous to a single pole, single throw switch with one terminal connected to power common. This circuit layout is commonly called an Open Collector Output . (See

Figure A-1 .)

Capability limits of a CCO are as follows:

• 50 mA maximum current flow when closed.

• 30 V dc maximum tolerance voltage when open.

A CCO will operate any external device that can be made to switch if it does not require more than 50 mA of current to the (+) terminal.

Typical uses for a CCO are to actuate a small relay, activate an external alarm buzzer, provide Contact

Input (CCI) to another instrument, or to provide output to an annunciator panel.

A CCO circuit is equivalent to an unpowered switch. If the 24 V de supply of the instrument is not already fully loaded

1

, it can be used as a source of power for the CCO; otherwise, a separate, external dc supply

must be used. In the upper circuit illustration of Figure A-2

, the +24 V is obtained from pins 1 or 4 of TB1

located on the instrument rear terminal board. (See Figure 2-4 .)

In

Figure A-1 ,the switch is closed when the output logic bit (L24 for CCO0) is set to

1 , provided that its respective invert bit (L288 for CCO0) is 0

. The relay in Figure A-2

is energized when the output bit is set to

1 if the invert bit is 0 . If the invert bit is set to 1 , the output bit will cause the relay to de-energize when it is set to 1 .

Figure A-2 also shows how a dc electromechanical relay is operated using an internal or external power

source. There are many dc relays available with a coil resistance of 430 ohms or more.

(Note: with the 24 V dc supply, a 430 ohm coil resistance will pass 50 mA of current.)

Figure A-3 shows how several CCOs can be arranged in parallel using one power source, so that any one

CCO can actuate a single relay.

Figure A-4 shows a CCO used to control a solid state relay

2

. The resistor is added to the circuit from the power source to limit the current flow, and also to establish the voltage across the relay when the CCO switch is open.

In

Figure A-5 , the CCO of one instrument is applied directly to the CCI of another instrument. When the

CCO closes, the CCI circuit of the second instrument is complete. An appropriate resistance is required in the second instrument, as it provides the power for its CCI operation.

Appendix B: Communications

B.1 Standard Communications

Two digital communication channels are provided with this instrument:

1.

There is a configuration port that is an RS-232 serial interface. It is accessed via a 5 pin mini-DIN connector located under the pull-down door on the front panel (see

Figure 3-1

). It is used to configure instrument parameters for selected operational characteristics. The parameters are configured with the Hand-Held Configurer (HHC), as described in

Section 3

, or with a customer-supplied PC executing the appropriate software.

2.

There is also an RS-422/485 serial interface used to connect the instrument to a Datalink multi-drop network. Interface connection to the Datalink network is via the rear terminal board

(TB1) of the instrument, pins 19 through 22, as shown in Section 2

.

Information in this section applies to both the configuration port and the Datalink interface, with the following exceptions:

1.

The configuration port data rate is 9600 baud, with 8 data bits, and no parity.

2.

The configuration port powers up in standard mode suitable for use with the HHC, but can be switched to binary mode by sending the following four-character sequence:

Sent 03H 1 BH 0EH 15H

Echoed 1BH 20H 0EH 20H 15H

Note Numbers used in this section that are expressed In hexadecimal notation (base 16) are identified with an H after the number.

After echoing the 15H character, the instrument switches to binary mode and is able to process binary communications messages from that time on. (Characters sent after the 15H and before the 15H echo are ignored.)

3.

Once the configuration port switches to binary mode, it remains in that mode as long as the connection is maintained. The connection is maintained by sending a character at least once every 30 seconds. If 30 seconds elapses without a character being received by the instrument through the configuration port, the port returns to standard mode.

4.

When in binary mode, the instrument responds to all messages regardless of the address to which they are directed.

The Datalink interface requires four conductors: a transmit pair and a receive pair. The voltage levels of each conductor pair conform to the EIA RS-422/485 standard. In accordance with this standard, the overall

Datalink network distance is limited to 4000 feet when #24 AWG twisted pair wire is used to interconnect the nodes. Adapters are available to convert RS-422/485 to RS-232 or 20 mA current loops.

In a Datalink network, the instruments communicate as Responders to host or SUPERVISOR-PC queries.

The host or PC functions as the Interrogator and acts as the central control point for the Datalink network.

A maximum of 32 addressable instruments can be connected to a Datalink network. Using the

SUPERVISOR-PC in a Datalink network system allows a variety of services to be implemented as described in the SUPERVISOR-PC Instruction Bulletin , IB 53SU5000.

B.1.5 Calculating Data Addresses

If communications software must be generated to accommodate unique Datalink applications requirements, then the instrument memory address scheme must be known for proper data bit (e.g., L data type) and data byte (e.g., B, C, H, and A data types) memory location determination.

Note Numbers used in this section that are expressed in hexadecimal notation (base 16) are identified with an H after the number.

This memory address scheme applies only if a 6 is in memory address location 8002H. Memory address location 8002H must be read and if it contains a 6 , then the address scheme that is described in

Table B-3

should be applied for this instrument..

Represents a positive integer with values from 0 to 255.

A single binary bit with a logical value of 0 or 1. L datapoints are packed 8 to a byte.

Address = B Base + (B Number)

= 200H + (B Number)

Address example: B012 location

= 200H + 12D = 200H + CH = 20CH

Address = L Base + (L Number/8)

= 500H + (L Number/8)

Remainder = bit position in byte

Address example: L014 location =

500H + 14/8 = 501H, bit 6

(remainder).

Represents floating point values that have a resolution of one part in

32,768 (15 bits) and a dynamic range of ± 10

. The first two bytes represent a 2’s complement notation in fractional form (2

-n

) whose absolute value is between

0.5 and 0.9999. The third byte is the power of 2 in 2’s complement notation. Floating point example:

64H 00H 07H = 100D (Decimal)

64H = 0110 0100, fractional binary weights left to right are

0 = 2’s complement positive,

The first four bytes represent a 2’s complement notation in fractional form (2

-n

) whose absolute value is between 0.5 and 0.9999. The fifth byte is the power of 2 in 2’s complement notation. Floating point example: 9CH 00H 00H 00H 07H =

-100. The 2’s complement notation bit in the 9 = 1 (1001) indicating a negative number; therefore, 9C must be re-complemented . 9C =

1001 1100, change 1’s to 0’s and

0’s to 1’s = 0110 0011and add

07H=128D, 128D X 0.78125D =

100. A negative sign is assigned (-

100) because the original 2’s complement binary bit in the 9

(1001) of 9C was set indicating a negative number.

Address = H Base + (5 X H Number)

Address example: H001 location

F00H + (5 X 1) = F00H + 5D = F00H

When in Auto, this is the actual result of the controller

PID algorithm; otherwise, it is the value determined by the output pushbuttons. it is transferred to ANO0.

This parameter is the point in engineering units at which the upper alarm is triggered.

This parameter is the point in engineering units at which the lower alarm is triggered.

This parameter sets the activation/deactivation gap for the alarm. This value in engineering units defines an area of hysteresis at the alarm point.

This parameter is the percent of error required to move the output full scale for proportional action. It modifies the controller response in standard PID terms.

This parameter represents the number of minutes per repeat for integral action. It modifies the controller response in standard PID terms.

This parameter represents the minutes that proportional action is advanced (derivative action).

This parameter determines the position of the valve

(output) when the instrument is in Automatic mode and the error is zero. (It is only in effect when TR = 0.)

These two parameters set the upper and lower values on the controller display. They permit the control action to be defined over a range independent of the process variable input range. They also determine the speed at which the setpoint changes when the U P or D OWN arrow pushbuttons are pressed (CS1 through CS3).

For CS4, they determine only the displayable range, as the setpoint pushbuttons are not used.

It is the calculated result of the remote setpoint algorithm and is used as the setpoint if the controller is in remote.

This determines the upper range that analog input 0 represents in engineering units. The upper range value equals Engineering Zero plus Engineering Span.

This determines the upper range that analog input 1 represents in engineering units. The upper range value equals Engineering Zero plus Engineering Span.

This is the lower range value of analog input 0.

It indicates the Auto/Manual state of the controller. It is the logical AND of the Auto Switch (L112) and Auto

Enable (L114). A 1 for this bit indicates auto; a 0 for this bit indicates manual.

It indicates the Remote/Local setpoint source for the controller. It is the logical AND of the Remote Enable

(L115) and the Remote Switch (L113). A 1 for this bit indicates remote; a 0 for this bit indicates local.

This parameter provides information for the various control displays to indicate which direction the control output must go to close the final control element. A 1 indicates that 20 mA closes the valve. A 0 indicates that

20 mA opens the valve.

See Control Alarm Mode (B335) for PA1 states assigned to alarm modes 0 - 6.

See Control Alarm Mode (B335) for PA2 states assigned to alarm modes 0 - 6.

This logic bit indicates the state of the A/M pushbutton setting. It is a 1 if in auto and a 0 if in manual.

This logic bit indicates the state of the R/L pushbutton setting. It is a 1 if in R and a 0 if in local.

When a 1 , this logic bit permits auto control based on the state of the Auto Switch (L112).

When a 1 , this logic bit permits remote operation based on the state of the Remote Switch (L113).

Under normal operation, whenever the controller is powered up, the Auto/Manual Selector is forced to the

Manual position. When this datapoint is set to a 1 , the selector will not be forced to the Manual position at power up, but will remain in the last position before power was removed.

This datapoint indicates if Datalink parity generation and checking should be turned on or off. It is set to 0 for even parity serial byte protocol. It is set to 1 for no parity protocol.

When set to 0 , it permits full Datalink communication capabililties. When set to 1 , it disables Datalink communication capabilities.

Attribute

When set to a 1 , this datapoint disables the standard

MicroMod communication protocol feature which inserts a 00 (NUL) byte after every 7EH (SOH) that is not the beginning of a message. (This permits user-written communications software to determine the number of bytes to expect in a response message.) It must be set to

0 when using MicroMod communications software or equipment.

This bit reverses the action of CCI datapoint L000

(Contact Input); therefore, the action of this bit is explained in datapoint L000.

This bit reverses the action of CCO datapoint L024

(Contact Output); therefore, the action of this bit is explained in datapoint L024.

When this value is 1 , the datapoints in this module can not be altered with the pushbuttons. The values of these datapoints are only for display purposes. When this value is 0 , the datapoints in this module can be altered by the operator with the pushbuttons when this module is displayed.

Setting this parameter to 1 indicates the input range is from 0 - 5 volts (0-20 mA) for ANI0. A 0 indicates the input range is from 1 - 5 volts (4-20 mA) for ANI0.

Setting this parameter to 1 indicates the input range is from 0 - 5 volts (0-20 mA) for ANI1. A 0 indicates the input range is from 1 - 5 volts (4-20 mA) for ANI1.

When a 0 , it indicates the analog input 0 signal should be interpreted linearly.

When 1 , it indicates the analog input signal should be interpreted as a square root representation of the value.

When square root is selected, input signals less than 1%

(10% input range) force the input to its zero value.

When a 0 , it indicates the analog input 1 signal should be interpreted linearly.

When 1 , it indicates the analog input signal should be interpreted as a square root representation of the value.

When square root is selected, input signals less than 1%

(10% input range) force the input to its zero value.

When a 0 , the percentage output of ANO0 generates a

4-20 mA signal. When set to 1 , the percentage output of

ANO0 generates a 0 - 20 mA signal.
